Bitfuse
A digital payments platform shaped around the connected work of identity checks, wallets, transaction records and payment verification.
01 · Context
The setting
Digital payments depend on more than a transfer button. Identity, payment status, wallet balances and financial records need to make sense together across a complete transaction lifecycle.
02 · Problem
What the system needs to solve
The product needs to support KYC, payment initiation and verification, wallet activity and a ledger model without treating those concerns as separate screens or disconnected services.
03 · Approach
Make the workflow clear
Frame the product around explicit actors, transaction states and trustworthy records. Keep identity review distinct from payment processing, then make each state legible to the API and the people operating the system.
04 · Architecture / workflow
A view of the system in motion.
A project-level workflow based on the documented scope.
- 01KYC review
- 02Payment intent
- 03Verification
- 04Ledger entry
- 05Wallet view
05 · Technical implementation
What the implementation covers.
- Product scope covers KYC workflow, transaction lifecycle, wallets, ledger architecture, payment verification and API/backend architecture.
- Security and operational considerations are part of the system design, not an afterthought to the payment interface.
06 · Key decisions
Designing for the system, not just the screen.
These notes focus on system-level decisions; undocumented implementation and deployment details are not inferred.
- Model the transaction lifecycle explicitly so a pending, verified or failed payment is not mistaken for a completed one.
- Treat the ledger as the record of financial movement; derive wallet views from recorded activity rather than an unexplained balance change.
- Keep verification and operational review visible in the API workflow, with security considered at the system boundary.
